Probably only a small form, says J. D. Hooker, of R. Emodi, Wall., with acuminate leaves, but the flowers are considerably larger, and, though long under cultivation, it does not attain half the size of that plant or vary in its character. Stem leafy ; leaves long-petioled, triangular or orbicular, ovate, acuminate ; base cordate, 5-7-nerved, panicles papillosely puberulous, fastigiately branched and leafy ; flowers red ; fruit ovoid, oblong, base, cordate, tip entire or notched, wings narrower than the nucleus.
